I have to fully disagree with a lot of what you say. There is no reason why everything you talk about - cost, fuel efficiency and alternative fuels can't be worked into F1, ALONG with faster. Heck, in many ways, in racing they go hand in hand.If I can make an engine that is just a big more fuel efficient than the competitor, that means less pit stops, thus results in a better chance to win. Same holds w/ alternative fuels.In the end the Sponsorships provide a very FINAL proving ground that can't be matched in CAD or anything else. Designs that are so cutting edge a computer has no clue, can be tested in reality and the results can be studied.In this end - could this be a big, short term money saver? Sure. But could it also cost Bridgestone a big opportunity to improve in the future and make even more money? Yes.
